Method Summary

static java.lang.String	getId(ru.novosoft.uml.foundation.core.MModelElement me) Get the XMI id of an NSUML element
static int	getLowerMultiplicity(ru.novosoft.uml.foundation.data_types.MMultiplicity multiplicity) Get the lower bound of any range of a multiplicity.
static int	getUpperMultiplicity(ru.novosoft.uml.foundation.data_types.MMultiplicity multiplicity) Get the upper bound of any range of a multiplicity.
static boolean	isMultiple(ru.novosoft.uml.foundation.data_types.MMultiplicity multiplicity) Show whether a multiplicity can have multiple instances, according to the following rules: if getLowerMultiplicity(ru.novosoft.uml.foundation.data_types.MMultiplicity) and getUpperMultiplicity(ru.novosoft.uml.foundation.data_types.MMultiplicity) both return StructuredType.UNBOUNDED, assume the multiplicity has not been specified and defaults to 1, so return false if getUpperMultiplicity(ru.novosoft.uml.foundation.data_types.MMultiplicity) is greater than 1, return true if getLowerMultiplicity(ru.novosoft.uml.foundation.data_types.MMultiplicity) is greater than or equal to zero, and getUpperMultiplicity(ru.novosoft.uml.foundation.data_types.MMultiplicity) is UNBOUNDED, return true

Method Detail

getId

public static java.lang.String getId(ru.novosoft.uml.foundation.core.MModelElement me)

Get the XMI id of an NSUML element

Parameters:

me - the element of which the id is required

Returns:

the XMI id of the element

getLowerMultiplicity

public static int getLowerMultiplicity(ru.novosoft.uml.foundation.data_types.MMultiplicity multiplicity)

Get the lower bound of any range of a multiplicity.

Parameters:

multiplicity - the MMultiplicity of which the lower limit is required

Returns:

the lowest number of instances, or StructuredType.UNBOUNDED.

getUpperMultiplicity

public static int getUpperMultiplicity(ru.novosoft.uml.foundation.data_types.MMultiplicity multiplicity)

Get the upper bound of any range of a multiplicity.

Parameters:

multiplicity - the MMultiplicity of which the upper limit is required

Returns:

the greatest number of instances, or StructuredType.UNBOUNDED if there is no upper limit.

isMultiple

public static boolean isMultiple(ru.novosoft.uml.foundation.data_types.MMultiplicity multiplicity)

Show whether a multiplicity can have multiple instances, according to the following rules:

• if getLowerMultiplicity(ru.novosoft.uml.foundation.data_types.MMultiplicity) and getUpperMultiplicity(ru.novosoft.uml.foundation.data_types.MMultiplicity) both return StructuredType.UNBOUNDED, assume the multiplicity has not been specified and defaults to 1, so return false
• if getUpperMultiplicity(ru.novosoft.uml.foundation.data_types.MMultiplicity) is greater than 1, return true
• if getLowerMultiplicity(ru.novosoft.uml.foundation.data_types.MMultiplicity) is greater than or equal to zero, and getUpperMultiplicity(ru.novosoft.uml.foundation.data_types.MMultiplicity) is UNBOUNDED, return true

Parameters:

multiplicity - the MMultiplicity which may be multiple or not

Returns:

true if multiple instances are allowed.
